Objective We present the case of a 6-year-old boy with a coarse face, cleft palate, and malocclusion with anterior open bite who had been diagnosed with Simpson-Golabi-Behmel syndrome. Morphology of the craniofacial structures was examined on the basis of conventional radiographs, three-dimensional (3D) computed tomography (CT) and magnetic resonance (MR) scanning. Patient This patient had 13 ribs on the right side, slight scoliosis, supernumerary nipples, a coarse face, hypertelorism, a short broad upturned nose, a wide mouth, a straight facial profile with incompetence of the lips, midline groove of tongue, and cleft palate. The patient also had severe anterior open bite, a distal step-type molar relationship, five congenitally missing teeth, and a supernumerary tooth. Lateral cephalometric analysis revealed a large anterior cranial base, a large maxilla and mandible, a large inferior face height, and skeletal Class I jaw relationship with a high mandibular plane angle and large gonial angle. The 3D CT image showed a large cranium, a long face height, and prominent skull sutures. The MR image showed a large tongue, midline groove of the tongue, and a small space between tongue and palate.

Objective To examine the three-dimensional morphology of internal structures of the craniofacial region and present the orthodontic problems in an unusual case with nasal aplasia. Patient The patient was an 11.5-year-old boy with aplasia of the nose and nasal cavity with extremely constricted nasopharyngeal airway. He did not have mental or somatic retardation. The patient had dacryostenosis. The morphology of the craniofacial structures was characterized by absence of septal structures, including cribriform plate, perpendicular plate of ethmoid bone, vomer, and septal cartilage; bony hypotelorism; midface hypoplasia; short and retrognathic maxilla with Class III jaw relationship; average mandibular plane angle; high arched palate; severe anterior open bite with bilateral posterior crossbites; and dental anomalies (agenesis of four maxillary permanent teeth, microdontia, taurodontism, and short roots). Thus, the patient had characteristic dentofacial phenotype, which might be caused by a combination of the primary anomaly and the functional disturbances secondary to the nasal obstruction.

ABSTRACT Objective: To evaluate the three-dimensional (3D) skeletal changes in the mandibles of Class III patients treated with bone-anchored maxillary protraction using shape correspondence analysis. Material and Method: Twenty-five consecutive patients with skeletal Class III who were between the ages of 9 and 13 years (mean age, 11.10 ± 1.1 years) were treated using Class III intermaxillary elastics and bilateral miniplates (two in the infrazygomatic crests of the maxilla and two in the anterior mandible). Cone-beam computed tomography (CBCT) was performed for each patient before initial loading (T1) and at 1 year out (T2). From the CBCT scans, 3D models were generated, registered on the anterior cranial base, and analyzed using 3D linear distances and vectors between corresponding point-based surfaces. Results: Bone-anchored traction produced anteroposterior and vertical skeletal changes in the mandible. The novel application of Shape correspondence analysis showed vectors of mean (± standard deviation) distal displacement of the posterior ramus of 3.6 ± 1.4 mm, while the chin displaced backward by 0.5 ± 3.92 mm. The lower border of the mandible at the menton region was displaced downward by 2.6 ± 1.2 mm, and the lower border at the gonial region moved downward by 3.6 ± 1.4 mm. There was a downward and backward displacement around the gonial region with a mean closure of the gonial angle by 2.1°. The condyles were displaced distally by a mean of 2.6 ± 1.5 mm, and there were three distinct patterns for displacement: 44% backward, 40% backward and downward, and 16% backward and upward. Conclusion: This treatment approach induces favorable control of the mandibular growth pattern and can be used to treat patients with components of mandibular prognathism.

The craniofacial morphology of 11 pairs of monozygotic (MZ) and 28 pairs of dizygotic (DZ) Finnish twins, discordant or concordant for cleft of the lip (CL), unilateral cleft lip and palate (UCLP), or cleft palate only (CP) were investigated by means of lateral cephalometric radiographs. The results were compared to those of age-, sex-, and cleft-type matched single-birth cleft subjects, and also with normative data from the Nordic population. The co-twins with no cleft lip or palate (NONC) showed only slightly more obtuse gonial and steeper mandibular angles compared to normative data. Twins with CL, UCLP or CP had a more retrusive mandible, a wider cranial base and mandibular angle, and a wider angle between the maxilla and mandible than did the single-birth cleft subjects. Comparison of the noncleft twin group with the CL, UCLP, and CP twin groups for the CL twins showed no significant differences. For the UCLP twins, a more retrusive and down- and backward rotation of both jaws, a wider gonial angle, and a wider cranial base angle was seen. The CP twins had their maxillae slightly retrusive, the down- and backward rotation of both jaws was apparent, and the gonial angle was more obtuse. A comparison between the noncleft MZ and noncleft CDZ twins showed no significant differences. The MZ CP twins had a more retrusive mandible and more down- and backward rotation of both jaws than did DZ CP twins. It thus can be suggested that twinning itself does not seem to have an effect on maxillofacial morphology, but the features of the mandibular structure, the cranial base angulation, and the inclination of the jaws are at least partly genetically induced.

Adequate planning and early treatment of Angle Class II malocclusion with maxillary atresia and anterior open bite provides harmonization of maxillomandibular bone bases in the three planes of space. Orthodontic aligners have emerged as an alternative treatment having the following advantages: being more aesthetic and more comfortable for the patient, less treatment time when they are correctly indicated, less chairside time, less complications, possibility of remote monitoring, easier feeding, and dental hygiene. On the other hand, they offer difficulties to treat adults with severe skeletal Class II malocclusions, posterior crossbite and anterior open bite. Therefore, the objective of this clinical case report is to early correct skeletal Class II malocclusion with maxillary atresia through the use of mechanical orthopedics and devices that help eliminate habits and close the anterior open bite, and later the use of orthodontic aligners to finish the treatment. It was concluded that the early interceptive treatment of malocclusion was efficient to harmonize the bone bases in the anteroposterior, vertical, and transversal directions, changing this malocclusion from high to low complexity and, consequently, highly predictable and with an excellent prognosis for treatment with orthodontic aligners. The treatment with ClearCorrect aligners corrected the occlusion in a shorter period of time when compared to corrective orthodontics and with a high predictability in relation to the virtual setup.

The present case report describes a conservative and uncommon treatment for class III malocclusion in a woman growing patient with aged eight years and four months. An unconventional treatment modality was used for the treatment of this malocclusion, reverse-pull headgear and distalisation of lower teeth using mandibular cervical headgear in the lower arch. At the end of the treatment (after 33 months), there was correction of the transversal and sagittal occlusal relationship between maxilla and mandible and correct dental intercuspation.

Kallmann’S Syndrome

Objective: Kallmann's syndrome is characterized by the association of hypogonadotropic hypogonadism and anosmia or hyposmia. The principal endocrine defect of hypogonadotropic hypogonadism is a failure to secrete luteinizing hormone-releasing hormone (LHRH), resulting in underdevelopment of the pituitary gonadotropes and an inability to synthesize and release luteinizing hormone and follicle-stimulating hormone. The purpose of the present investigation was to describe the dentition and the craniofacial morphology in patients diagnosed with Kallmann's syndrome. Design: The sample consisted of 11 patients, 2 of whom also had bilateral cleft lip and palate. Radiographic investigations, including cephalometry, were performed. Comparisons were made to normal individuals and to cleft lip individuals without Kallmann's syndrome. Results: Dentition: tooth agenesis occurred more frequently in patients with Kallmann's syndrome. Craniofacial morphology: Increased mandibular inclination and mandibular angulation were seen in Kallmann patients. When clefting also occurred, extreme retrognathism of both maxilla and mandible was seen, a deviation which seemingly worsened during growth. The anterior cranial base and the sphenoid bone showed an altered morphology in one of the patients with Kallman's syndrome. Conclusions: An early diagnosis of Kallmann's syndrome is very important because the prognosis for endocrine treatment thereby improves, and therefore, it is recommended that the sense of smell be evaluated in patients with the craniofacial morphology described.

ABSTRACT This report illustrates the successful nonsurgical and nonprosthetic camouflage treatment of a skeletal Class II open bite malocclusion combined with missing mandibular first molars bilaterally. In the mandible, the second and third molars were uprighted and protracted, substituting for the missing first molars. In the maxilla, anterior bodily retraction and full-arch intrusion were achieved following premolar and second molar extraction, which also induced autorotation of the mandible. The treatment outcome and prognosis were confirmed with three-dimensional superimposition techniques, along with long-term stability.
